This question is very easy to answer: SunCatcher are made of a special fluorescent acrylic. Like standard acrylic is has all the great features acrylic has: It is frost, weather and water proof and will never rust, e.g. For SunCatcher material a fluorescent substances has been added during manufacturing giving fluorescent ability to the acrylic. Fluorescence is know for some time and can be found in nature among scorpions, birds, insects, minerals and bacteria. All these emitting the same light SunCatcher do. Humans don’t usually notice, because the colours appear brighter, more luminous or more intense to the human eye only – who would think of fluorescence?
But our SunCatcher have another trick up their sleeve:
If the humans eye can hardly recognize the glow, why do my SunCatcher shine in the most vibrant colours?
Acrylic can be highly transparent. It only shines where floodlid. SunCatcher’s fluorescent acrylic collects invisible UV light on its entire surface and produces visible light or luminaires. But still this would be difficult to see with a human eye. Luckily acrylic has very few pores and is extremely smooth. It reflects light almost without loss. SunCatcher direct all produced light to their edges by reflecting it internally until it reaches an exit. Accordingly, as bigger the surface of a SunCatcher, as more light can be collected and as stronger it will shine. When the light leaves the SunCatcher it create this magical, mysterious shine.
Next to the edges light can leave a SunCatcher on two more ways:
a) Genuine SunCatcher are engraved. Always check if you find our brand or our website on the surface. This underlines the fine quality of original SunCatcher and marks them as a quality product. Engraving is similar to carving; it alters the smooth surface of the acrylic. As soon as the surface changes a new exit is formed and the pattern, ext or image will start to shine.
b) When it rains (and it rains a lot here in Scotland) rain drops will fall on the surface of your SunCatcher. Water can alter the surface of the your SunCatcher and the drops will shine as well creating an even more colour highlight in your garden.
